Even when we show ignorables, we still want to
ignore variation selectors and other ignorables
that we don't have nicks for.
Test included.
|
| |
|
|
|
|
| |
Add some more directional formatting characters
to the list of default-ignorables that we make
visible when requested: ALM, LRI, RLI, FSI, PDI.
|
| |
|
|
| |
No need to walk to the end if we are done.
|
| |
|
|
|
| |
We don't necessarily want to depend on a newer version of GLib, given
that we're not really using g_memdup() in the wrong way.
|
| |
|
|
|
| |
Use hb_font_get_nominal_glyph in pango_win32_font_get_glyph_index
(deprecated), to better match what Pango is actually using internally.
|
| |
|
|
|
|
|
| |
This returns nicknames and formatting information
for default ignorable characters. This will be
used to render customized hex boxes for these
characters.

Variant of pango_shape() that takes the full paragraph text as input.
This is then passed in entirety to HarfBuzz, which would allow certain
cross-run interactions (in Arabic for example).
When combined with upcoming HarfBuzz 0.9.5+, this fixes:
Red Hat Bug 858736 - [Spanish] Stray dotted circle rendered
https://bugzilla.redhat.com/show_bug.cgi?id=858736
and partially:
Bug 313181 - color changes break arabic shaping
https://bugzilla.gnome.org/show_bug.cgi?id=313181

Fixed all modules to reverse glyphs if run is rtl. Except for Hangul module.
Fixed pango_shape() to detect that, warn, and reverse.

While pango-layout doesn't allow NUL in text, the lower level API should
handle it correctly. We were using g_utf8_strlen() in a number of
places. This is problematic since that function stops processing at
NUL even if length>1. We now use an internal pango_utf8_strlen() instead.
Inspired by:

Bug 563356 – The input area of firefox and the blank width after text
in gnome-menu was stretched too wide, under pango-1.22.3
* docs/tmpl/fonts.sgml:
* pango/pango-impl-utils.h:
* pango/pangocairo-atsuifont.c
(pango_cairo_atsui_font_create_metrics_for_context):
* pango/pangocairo-win32font.c
(pango_cairo_win32_font_create_metrics_for_context):
* pango/pangofc-font.c (pango_fc_font_create_metrics_for_context):
For approximate_char_width calculation take each char's width into
account. That is, do a weighted average instead of uniform average.
g_unichar_iszerowidth() chars count as 0, g_unichar_iswide() chars
count 2, and the rest count as 1. Pretty much wcwidth() behavior.
See bug report for rationale.

Bug 478914 – Use something invalid instead of '?' when validating
input text

Hook up pango-utils.h into the documentation, as we are installing
it anyway. Move some internal stuff to pango-impl-utils.h and make
source files include that instead.
